Cedar
Trim planning.
“Cedar” is a broad buying term, not a complete specification. Species, grade, heartwood content, grain orientation, moisture and finish determine what reaches the job. Complete corners, fascias, openings, bands and material transitions with widths and thicknesses that align to the cladding, flashing and finish strategy.

Name the cedar species, grade, moisture condition, face, profile, heartwood expectations and finish—not only “cedar.”
Trim succeeds when it is integrated with the water-management layer. Define projections, joints, end conditions, flashing and fastening before selecting a wide board.
Availability, color, grain and natural durability can vary substantially between cedar products and grades.
The prefinish advantage
Coat the board
before access disappears.
Cedar accepts many finish systems, and industry guidance recommends pre-priming or prefinishing before delivery for optimum siding and trim performance. Shop prefinishing is especially valuable on wide trim and fascia because backs, ends and top edges are hard to reach after installation and visually obvious coating variation can create callbacks.
Plan a prefinished packageControlled coverage
Confirm whether faces, backs, edges and ends are included, plus coating manufacturer, color, sheen and target coverage.
Cleaner schedule
Move eligible coating work away from installed assemblies, ladders, lifts and interference with other trades.
Consistent appearance
Controlled application and cure conditions can reduce lap marks, streaks and unfinished shrink lines.
Field discipline remains
Reseal cuts, holes and damaged coating; protect finished boards in storage and follow the approved touch-up process.
A quote-ready scope
Four questions
before material selection.
Coordinate trim with flashing and the enclosure. Wide boards still need correct storage, acclimation, fastening and movement detailing.
- 01Fascia, corner, opening or transition?
- 02Required width, thickness and projection?
- 03Flashing and end-grain details?
- 04Match or contrast the field material?

Material planning FAQs
Specify first.
Price second.
Is Cedar automatically the best choice for wood trim and fascia?+
No. Cedar has useful strengths, but the decision still depends on exposure, grade or product, profile, assembly, finish, maintenance and budget. This guide makes those inputs visible before a quote is requested.
Can Maximo Thermo be used for this trim project?+
Only when the exact profile is documented for the intended application. The profiles shown here are selected from the closest cataloged application, but the project team and BFS Issaquah should confirm the final profile and assembly.
Why discuss prefinishing before installation?+
Shop prefinishing is especially valuable on wide trim and fascia because backs, ends and top edges are hard to reach after installation and visually obvious coating variation can create callbacks. Prefinishing does not eliminate field-cut sealing, touch-up, installation care or future maintenance.
Where can I ask about availability in Issaquah?+
Submit the project brief through this site or contact Builders FirstSource Issaquah. This site does not claim live inventory, pricing or guaranteed lead time.
